well he always was insecure about preeta...not that Preeta helped in any way making it better... she is so extra sweet with Rishabh, feels artificial most times...yet she doesn't have feelings for him...Karan she loves but kept quarrelling with him... And TKL was never known for his intelligence was he😆yaar party main hi confront kar leta donon say. Tabhi Sab solve ho jaata. It just shows deep inside he was insecure of Preeta Rishabh friendship.
